IMPROVED SNOW-PLOW.

T0 ALL WHVOM ITV MAY CONGERN:

B e it known that I, SAMUEL LEWIS, of Brooklyn, in the county of Kings, in the Stato of New York, have invented a new andimproved Snow-Clearer'; and I do hereby declare that the following is a full and exact description `ofthe construction and operation ofthe same, reference being had to the annexed drawings, making a part of this specication, and the figures of reference marked thereon.

The object sought in this invention was a greatly increased expedition and reduction of expense in the clearing of the surfaces of skating-ponds und ice-lakes after a fall of snow. Experience has demonstrated how 'susceptible these 'items were of a profitable modification.

' The practice has heretofore been, and is now, with all men (save the present applicant) who are practically interested in skating-ponds or ice-getting, to attach two, three, or four men to each clearer or plow, according to thesize or capacity of the machine, one to drive and the others to follow and. lift the implement when it has collected a load. This labor, frequently performed ankle-deep in` snow-slush, is a serious tax upon the exchequer of au establishment and the vital energies and health of employes; it is slow, expensive, and exhausting. The labor and cost, however, heretofore inseparablefrom the removal of snow from extended surfaces,

havebeen greatly reduced `by the invention illustrated bythe accompanying drawings, (similar numbers indicating corresponding parts in the three gures,) in which- Figure I is' a vertical longitudinal section in the line-*1*, Fig. III, showing the clearer in its two positions of collecting and discharging its load, the red lines indicating the latter. Showing, also, the position of the drivers seat 5, and the raising-apparatus, such as gearing 7 8, axle 10, pulleys 6 6 6 6 6, chains 12 13, (rear and one front,) legs 14 l5, (rear and one front,) guides 16 17, (rear and one front,) .&e.

` Figure II is afront elevation, as viewed from *1, or as you look into the interior of the machine, showing clearly the bracing, the metallic lining of the lower edge of the sides, the gearing-frame 4, the manner and points of attachment of the pulleys 6 6 6 6, the lines and connections of the front elevating-chains 11 12 from the front legs 14 14 to the axle 10, and the handle or lever 9, through which the whole mechanism is operated.

Figure III is a top or plan view, showing the draught-attachments 20, the upper bracing or .platform 3, the guides 17 18 19, the line of the rear clevating-chain 13, from the axle to its appropriate pulley and leg, and the general conguration of the clearer.

The novel features of' this machine will be seen to consist of' a series of pulleys, chains, gearing, and legs, the latter outside of all, and standing on the ice. The legs, at certain points, as shown, are' encircled by rings or guides, which latter serve to keep the former in placcand'position, and to-secure a parallel and even motion to the body of the clearer during its elevation and return downwards.

Nothing -is claimed specieally for the body ot' the machine in point of strength or otherwise, but I may call attention to the plan of bracing, and the additional feature of the draught-attachment, which, as itis connected with the sides, is constantly counteracting the spreading pressure of the load.

The management and operation of this clearer, i`n use, are as follows: The horse being hitched and the driver seated, the machine 'is drawn into the snow, of course unattendedby the usual following or waiting laborers. When a load has been collected, the driver heads for the appointed dumping-ground, which is generally on the margin of the surface to be cleared, on arriving at which he wheels into a line parallel with the ban'k, seizes the handle 9, gives one turn or so to the axle 10, raising the body of the machine to the position indicated by the red lines, and, without slacking 1his speed in the least, dashes olf for another load.

The apparatus, during its elevation, and while passing over the discharged snow, slides onthc legs 14 14 15. The load once clearedthe driver simply releases the handle, and 'gravity at once brings the whole down again upon the ice. v

Having thus described the construction and-opcration'of my improved snow-clearer, what I claim as new, and desire to secure by Letters Patent, is- Y The combination of the leverA 9, axle 10, gearing 7 8, chains 11, 12, 13, pulleys 6 6 6 6 6, legs 14 14 15, and guides 17 18 19, as set forth, to the body of a snow-plowfas ordinarily constructed, all as explained and specified.

SAMUEL LEWIS.
